USAF Deputy Undersecretary For Space Programs Gary Payton has told Defense News that President Obama’s proposal to cancel the Constellation program would have a “trivial” impact in terms of solid motor production costs. He also said the Air Force could benefit if NASA decides to use an existing expendable for human missions.
Q. Are you concerned about the Constellation decision’s impact on the solid-rocket motor industrial base?
A. We’ve come to find out that it has a trivial impact on space launch because we don’t use the big 3½-meter segmented solids on our EELVs; we use solids that are about 1½ meters in diameter. There is a small ripple effect into space launch, but the dominant industrial base concern, according to the Office of the Secretary of Defense for Industrial Policy, is on the ballistic missile side for the Navy and Air Force. We build 30 to 40 stages for the Trident D5 submarine-launched missile every year, and there are about a dozen motors built each year to sustain the Minuteman 3 industrial base. We already know these sustainment costs will go up, but we don’t yet know by how much.
